Additional null checks and comments
Add defensive coding to check for possible null pointer values, thus preventing certain potential runtime exceptions. Fix some minor spelling inconsistencies. Refactor some method signatures and update the Javadoc. Reformat Resource toString() method to avoid lengthy String concatenation and duplicated separators.
